Abstract
Both Otto Friedrich Gruppe and Conrad Hermann precede contributions by Carnap, Wittgenstein, and others to modern philosophy of language. Unexpectedly, the notions of language and meaning were introduced in the 19th century: in the Vormärz context, seemingly solely >modern< understandings of the relation between language and thought, are formulated convincingly; the rediscovery of this hidden ancestors of the linguistic turn sheds light on the understanding of central philosophical notions and the notion of modernity itself.
